EOSDIS New Datasets: October 2017

GHRC DAAC

NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) published beta versions of the Lightning Imaging Sensor on the International Space Station - LIS (ISS), non-quality-controlled standard products on September 17. These data are made available to users until a manual quality control process is complete, at which time they will be replaced by the archive version of the products.

These data are collected by the LIS (ISS) used to detect the distribution and variability of total lightning occurring in the Earth’s tropical and subtropical regions. These data can be used for severe storm detection and analysis, as well as for lightning-atmosphere interaction studies. The LIS instrument makes measurements during both day and night with high detection efficiency. The data are available in both Hierarchical Data Format (HDF)-4 and netCDF-4 formats. Data is available from 3/1/2017 forward.

GHRC DAAC published the Global Precipitation Measurement Ground Validation (GPM-GV) NASA S-Band Dual Polarimetric (NPOL) Doppler Radar Olympic Mountains Experiment (OLYMPEX) dataset. The dataset consists data and images from the NPOL radar during the GPM OLYMPEX campaign. NPOL, developed by a research team from NASA's Wallops Flight Facility, is a fully transportable and self-contained S-band (10 cm), scanning dual-polarimetric Doppler research radar that was placed near the ocean on the Olympic Peninsula, Washington. Data files are available from November 5, 2015 thru January 15, 2016 in Universal Format (UF), with browse imagery files in PNG format containing corrected radar reflectivity, differential reflectivity, specific differential phase, differential phase, co-polar correlation, and Doppler velocity images

SEDAC

NASA's Socioeconomic Data and Applications Center (SEDAC) datasets, Global Population Count Grid Time Series Estimates, v1 (1970-2000) and Global Population Density Grid Time Series Estimates, v1 (1970-2000), were released on 13 October as part of the SEDAC Population Dynamics data collection. These datasets represent a “back-cast” time series of population count and density on a 30-arc-second (~1 km) grid over a 30-year period, using as a baseline the year 2000 population grid from SEDAC's Global Rural-Urban Mapping Project, Version 1 (GRUMPv1) dataset. Subnational population growth rates were adapted from the History Database of the Global Environment (HYDE) database, and population grids were adjusted so that country population totals equal the UN World Population Prospects (2008 Revision) estimates for each country for the years 1970, 1980, 1990, and 2000. These grids were developed as an input to the dataset, Global Estimated Net Migration Grids By Decade, v1 (1970-2000).
